[Clinical and laboratory features of patients with CD34(+) acute promyelocytic leukemia].

Objective: To explore the expression of CD34 in patients with acute promyelocytic leukemia (APL) and investigate the clinical and laboratory features of CD34(+) APL patients.

Methods: 262 APL patients diagnosed by chromosome analysis and/or fusion gene examination in the last five years were retrospectively analyzed in this study. To survey the expression of CD34 in those patients, all the cases were divided into two groups (CD34(+) APL vs.

[Fluorescence in situ hybridization studies on a myeloid leukemia patient with ins(8;21)(q22;q22.1q22.3)].

Objective: To report a case of acute myeloid leukemia (AML) with the insertion (8;21)(q22;q22.1q22.3).

[The clinical and laboratory features of acute promyelocytic leukemia: an analysis of 513 cases].

Objective: To investigate the clinical and laboratory features of acute promyelocytic leukemia (APL).

Methods: 513 APL patients in the last two decades were retrospectively analyzed in this research. We investigated the clinical features including age, sex, abnormality of peripheral hemogram before treatment, therapeutic effect and follow-up and laboratory data such as morphology, immunology, cytogenetics and molecular biology (MICM).

[Immunophenotypic and cytogenetic features in 51 cases of chronic lymphocytic leukemia].

The study was aimed to investigate the immunophenotypic and cytogenetic features of chronic lymphocytic leukemia (CLL) in order to provide an evidence for diagnosis and therapy. Immunophenotypic analysis was performed by using a panel of monoclonal antibodies and three-color immunofluorescence staining methods of flow cytometry in 51 patients with CLL, and the cytogenetic features were analyzed by R-banding technique. The results indicated that among 51 CLL cases, the positive rate of CD19 and CD23 was 96.
